PROBLEM: (EVT101968) (Patch ID: OSF375-350334) ******** A system that boots and runs OK with 3 DE425s on an eisa bus may hang during boot if a 4th DE425 is added to the bus. The last message printed to the screen during boot is "eisa at pci0" or something similar, and then the system hangs. It does not respond to the halt button. PROBLEM: (Patch ID: OSF375-350334) ******** When devices with a "disable" feature are used, the ECU table must be modified manually when a device function is set to "disabled" because the system does not detect the change.
